Description
CONSTRUCTION PANEL AND INSTALLATION FOR ITS FABRICATION
DESCRIPTION
Field of the Invention This invention relates to a building panel and to ;3 plant for the manufacture thereof. To be precise, it relates to a lightweight panel for external or internal closures of latticework support structures, formed by uprights connected by horizontal crossmembers. The panE:l is formed by slabs of air-setting resistant material which are reinforced) in the facade panels for external closures and unreinforced in the dividing panels for internal closures and which have a patterned surface on ):he visible face thereof and a smooth or shaped surface at the edges thereof. The surface is formed by a thin layer of a synthetic resin or a fine mortar paste. The layer is formed as a shell partially enveloping a body of air-setting resistant material on which it confers a quality finish of architectural type with essential properties of resistance to weathering and environmental pollution and is formed in molding arrangements constituted by a mold-holder having an engraved bottom wall, on which there is seated the mold forming the 2o pattern of the visible face, the mold being made of polyurethane, silicone, etc and being surrounded by side members shaping the edges of the slabs.
This shell, after solidification, forms the mold for the said air-setting resistant material.
Prior Art Reference Building panels meeting the specifications contained in the foregoing generic description are known from Spanish Utility Model 9900014 of the present applicant. In said document there is contemplated the formation of the surface of the visible face and the edges of the panel 3o by molding at least three layers of synthetic resin.
Such building panels have drawbacks such as, in principle, the difficulty of forming an intimate bond between the synthEaic resin layer, forming the visible surfaces of the panel and the resistant body material, particularly when this material consists of an air-setting hydraulic material, such as a cement or lime mortar, concrete, plaster and the like.
To overcome this problem of bonding the two materials together, the solution was adopted of inserting between them a layer having affinity to s both, such as a layer of a hydrolysable resin. While the foregoing solution is generally sufficient for its task, it is delicate to carry out since it depends on many factors which are hard to control in industrial producti~an to the extent that, under extreme environmental conditions, the patterned layer may separate from the resistant material body.
1o Also, a further drawback detected in the panels clisclosed in the aforementioned Spanish Utility Model 9900014 is that the means provided for attaching the panel to a support structure are internal to the panel and are complex, artificious and hard to use, providing for unreliable attachment, which is quite unacceptable in a building, where these support 1 s structures are of lattice type formed essentially by metal upright sections which are connected by horizontal metal cross-member sections, with the ensemble being stabilized by strutting.
According to the regular practice, the facade panels are attached to the support structure by way of stirrups which are anchored in the mass of 2o the structure, by a tongue-and-grooved arrangement or engagement in notches in the openings of the structure and fixation thereof by masses of cement, by screwing, by welding of stirrups, frames or couplings to metal sections of the structure, etc. All these systems suffer from the drawback that they are complex, require scaffolding and shuttering in the majority of 2s cases, require specialized labor and are not absolutely reliable in situations of movement of the structure due to settling thereof, to th~~ action of gale force winds, earthquakes, explosions, etc.
Furthermore, when prefabricated panels reproducing architectural type patterns on the visible face thereof, such as stone masonry, brickwork, 3o carvings or other designs, are set side-by-side, the joints formed longitudinally and transversally therein are extremely obvious, breaking the aesthetics of the pattern design.

While the foregoing solution is generally sufficient for its task, it is delicate to carry out since it depends on many factors which are hard to control in industrial producti~an to the extent that, under extreme environmental conditions, the patterned layer may separate from the resistant material body.
1o Also, a further drawback detected in the panels clisclosed in the aforementioned Spanish Utility Model 9900014 is that the means provided for attaching the panel to a support structure are internal to the panel and are complex, artificious and hard to use, providing for unreliable attachment, which is quite unacceptable in a building, where these support 1 s structures are of lattice type formed essentially by metal upright sections which are connected by horizontal metal cross-member sections, with the ensemble being stabilized by strutting.
According to the regular practice, the facade panels are attached to the support structure by way of stirrups which are anchored in the mass of 2o the structure, by a tongue-and-grooved arrangement or engagement in notches in the openings of the structure and fixation thereof by masses of cement, by screwing, by welding of stirrups, frames or couplings to metal sections of the structure, etc. All these systems suffer from the drawback that they are complex, require scaffolding and shuttering in the majority of 2s cases, require specialized labor and are not absolutely reliable in situations of movement of the structure due to settling thereof, to th~~ action of gale force winds, earthquakes, explosions, etc.
Furthermore, when prefabricated panels reproducing architectural type patterns on the visible face thereof, such as stone masonry, brickwork, 3o carvings or other designs, are set side-by-side, the joints formed longitudinally and transversally therein are extremely obvious, breaking the aesthetics of the pattern design.
Thus, in facade panels imitating brickwork, where the bricks are arranged in break joint courses, it is obvious that a panel of this type will have at the vertical edges thereof bricks of one course whose edges coincide with the edge of the panel and bricks in adjacent courses which are split in half. This arrangement reveals the imitation, which is unaesthetic and impossible to hide with putties and the like. This is a limitation for the use of such facade panels imitating brickwork.
The same happens with facade panels imitating natural stone masonry, in which case it is much more difficult to disguise the straight lines of the joints, since the joints between the stones are very irrE~gular and in no case are they straight.
In other cases, which are very frequent in the nevv building trade techniques, it is normal to install internal plasterboard, fiberboard, etc slabs which are used in heterogeneous wall structures to accompany a prefabricated facade panel and form a thermal and acoustical insulation space in cooperation with another similar slab, in this Ease made from plasterboard which, acting as internal closure of the wall, forms the visible face thereof inside the room so formed. Thus, in the building trade, it is a regular practice, particularly in the case of buildings formed by a lattice 2o support structure formed by wooden beams or light metal sections, to attach the facade closure panels to the lattice supponr structure with screws, with the insertion of one of said internal plasterboard, fiberboard panels, etc.
This assembly system has the drawback that the movements due to settling of the structure, to the effects of wind, to snow loads, to seismic movements, structural vibrations, explosions or others cause relative movements between the members of the lattice structure and the facade panels, causing deterioration of said internal slabs by th~~ sawing action caused therein by the ensemble attachment screws, which changes the 3o distance between the lattice structure and the facade panels. As a result, the drawback arises that such panels are placed in a svvaying situation, leading not only to an aesthetic deterioration, but also to the risk of separation and, furthermore, the structure loses the strutting effect offered by said internal slabs.
Lightweight facade panels made substantially by individual molding of a mass of cement mortar with the inclusion of a metallic reinforcement, s such as the embodiments disclosed in Spanish patent 9900369 and utility models 9900014 and 9901847, of the present applicant, arE~ known. These are manufactured in known plants in which to prepare the prefabricated items of mortar or concrete, long heated tracks are used on which the molds are placed. Firstly, the reinforcement members are placed in them 1o and, thereafter, the mortar or concrete is poured and vibrated. After this, the molds are allowed to rest, until a sufficient degree of stating has been attained to be able to strip the molds and stack the pieces obtained until setting is complete.
These plants require large spaces to lay out the tracks, a high 15 energy consumption to heat the tracks, moving means f~~r placing and installing the reinforcement and other, also moving, means ~,~or pouring and vibrating the concrete, all of which means that such plants are extremely burdensome and hardly competitive, to which there should be added the enormous number of molds required for a profitable manufacturing 20 operation.
Summary of the Invention In view of the foregoing, it would be desirable to have a building panel fulfilling the largest number of the following conditions:
25 1. have unbeatable conditions of adhesion of the patterned layer to the material of the resistant body.
2. be provided with reinforcement means whicf i allow it to be attached to a lattice support structure, are easy to produce, may be accurately located and are completely reliable under 30 extreme conditions.
3. coordinate the attachment thereof to the lattice support structure with the attachment of inside wall internal slabs.
, CA 02378769 2002-O1-09 4. comprise a buttstrap arrangement hiding the joints between panels having an architectural pattern.
5. be simple and speedy to manufacture with High quality in a plant which is economical in equipment and labor.
s The building panel of the invention has been developed in accordance with the foregoing solution. Nevertheless, it may have other applications in decoration, industrial and civil protection, etc. In the panel, the molded synthetic resin layer, disposed as a shell ther~:in, is provided over the whole of the inner surface thereof with an internal layer, also of 1o synthetic resin, having the whole of the free surface thereof covered with a solid bulk material, the components of which, having a pact thereof firmly anchored to said internal layer, provide a substantial free surface for the anchorage of the resistant material of the body applied thereover, which material fills the entire volume of said panel shell, at the same time as it 1 s incorporates therein reinforcement means provided with points directly accessible from the outside of the concealed face of the panel.
According to the invention, the solid bulk material is preferably constituted by an aggregate having a large specific surface area and, more precisely, by a sand formed by sharp-edged angular, preferably non-eroded 2o grains. Also comprised within the idea of solid bulk matE:rial are metal shavings, metal fiber reinforcements, grit, etc.
According to the invention, the points of the internal reinforcement means accessible from the outside are located in such a way as to extend clearly from the surface of the concealed face of the panel. In any case, the 2s points of the reinforcement means accessible from the outside are formed by parts of said reinforcement means emerging from the resistant body of the panel on the concealed face thereof. Thus, in a particular case, the reinforcement means comprise flanged top-hat-shaped means having a portion of the U-shaped part thereof projecting from the outside level of the 3o hydraulic material on the concealed face of the panel, and the brim portions thereof are applied against the surface of the solid bulk material.
The invention also contemplates that the reinforcement means comprise metal sections forming the visible portion of the panel edges. One preferred embodiment contemplates that the section constituting the edges of the panel is an angle section and the web thereof is wider than the thickness the edges and is folded orthogonally and in parallel with the surface of the concealed face of the panel to form an anchorage tab which may have a stiffening flange directed towards the surface of said concealed face of the panel.
In all cases, it is deemed desirable that the methyl sections are provided with apertures in the webs andlor seating wings thereof allowing the mass of resistant material of the body to pass therethrough, so as to intimately to embrace a part of the metal section structure.
It is a further feature of the invention that some meval sections are situated lengthwise and others crosswise relative to the panel, forming a frame arrangement. In one case, the metal sections forrning the frame arrangement may be accompanied by other metal sections disposed parallel to one andlor the other of the longer and shorter sides of said frame arrangement and, in all cases, the metal sections comprise corrugated rods transversely crossing said frame and metal section arrangements, said rods being fixedly attached to points thereof, and also optionally accompanied by open mesh wire netting, meshes, etc.
2o According to the invention, the material forming the body resistant to mechanical stresses of the construction is one of the group formed by:
cement concrete, cement mortar, resin mortar, mixed hydraulic and resin mortar, plaster, lime mortar and synthetic resins, either normal or lightened, alone or in combinations thereof.
According to the invention, the resistant body of thE: panel may be formed by an inner layer of a heavy, air-setting resistant material, for the anchorage of the patterned layer and of part of the methyl reinforcement sections, and an outer layer of a lightweight resistant material, completing the body, conferring a greater thermal and acoustical insulating power 3o thereon and forming the concealed surface of the panel. Also according to the invention, the outer layer of the lightweight resistant material may be preformed as a prefabricated slab.
_'j_ According to the invention, the synthetic resin of the layer molded as a shell consists of a gel-coat of a resin of the group formed by polyesters, polyurethanes, phenolic resins and epoxy resins, either alone or in combination, incorporating, in all cases, a base coloring agent and, s optionally, ornamental and/or distinguishing surface coloring arrangements.
One aspect of the invention has a special application, in the building trade, in the above mentioned case of the assembly of the internal plasterboard slabs, fiberboard slabs, etc., where, according to the invention, the internal slab is applied directly, independently of the facade 1o panel, to the support structure, in such a way that it occupies one or more cells thereof and is flanked, in any case, by the corresponding upright and transverse sections, to which it is directly solely attached by screws or other means, at the wings thereof, or to another portion, at end points of the support structure lattice, occupying one or more of the cells thereof, in such 15 a way as to replace the conventional herring-bone strutting.
To avoid the problems appearing in panels having a surface decorated with architectural relief (brickwork, masonry, etc), with a view to disguising the joints between panels, according to the invention the edges of the sides of the panel to be placed juxtaposed to the sides of other 2o panels are provided, at the places on the visible face thereof where the joints cut across the relief of the pattern design, with slightly depressed areas, with those of an adjacent edge of one panel mating with those on the edge of the other panel. Once the panels are installed, these areas define depressed facade areas affecting part or the whole of the joint and in 25 which inserts bearing the design are fitted to form the continuation of the pattern design on the visible faces of the juxtaposed panels.
With a view to manufacturing the panel of the invention under the best conditions, a plant has been devised comprising ~~ track for the movement of carrier devices for the molds forming the facade panel on 3o which there are situated sequentially according to the operative stages required for the manufacture of the facade panel a number of work stations which, defined by the means andlor members pertaining to the work stage proper thereto are listed in order below:
_g_ (a) means for cleaning the molds andlor mold carriers, appropriate for removing any mortar and mold stripper remains deposited thereon, (b) means for changing the molds, to be used only when the s panel to be manufactured has different features from those of the panel which has been stripped from the mold, which means are complemented by shelving for case as a mold store, (c) means for applying a mold stripping product over the entire 1o molding surface, (d) means for spraying over the entire molding surface a thin layer of a first resin (gel-coat) which waterproofs and enhances the pattern of the visible face of the panel, (e) a tunnel with shelving for storing the molds in the carriers ~ 5 thereof, in stand-by for the curing of the resin sprayed in the molds andlor for the following operation on thE; mold, (f) means for spraying a thin layer of a second anchor resin on the first resin layer, (g) means for spraying a layer of coarse grained material (such 2o as sand, shot, etc.) on the second resin layer, so as partly to incrust said coarse grains in the resin and for removing the grains not adhering thereto;
(h) a tunnel with shelving for storage of the carriers bearing the molds charged with both resins and the coarse grains 25 incrusted in the second resin, in stand-by for the curing of the second resin and/or the following operation, (i) means for pouring cement mortar on the second resin and the coarse grains, which is prepared from the cement, aggregate, water and additives drawn from silos adjacent the 30 station, (j) means for placing the reinforcement in the cement mortar and, optionally, a suspension cable for the panel anchored in said reinforcement, (k) a tunnel kiln with shelving for the setting of the cement mortar, and (I) mold stripping means and shelving for stacking the finished panels.
A further feature of the invention resides in the face: that when the architectural features and the resins of the facade panels and, therefore, the polyurethane molds are not used, the molding surface is formed by the bottom wall of the mold carrier devices devoid of said molds, whereby the sequence of operative work stations is reduced to the following:
i0 means for cleaning (a) the mold-free mold carrying devices, appropriate for removing any mortar and mold stripper remains, means for applying (c) a mold stripping product over the entire molding surface, a tunnel with shelving (h) for storing the mold carrier devices, in stand-by for the following operation, means for pouring (i) cement mortar on the molding aurface formed by the mold carrier devices, which is prepared from the cement, aggregate, water and additives drawn from silos adjacent the station, 2o means for placing Q) the reinforcement in the cement mortar and, optionally, a suspension cable for the panel anchored in said reinforcement, a tunnel kiln (k) with shelving for the setting of the cement mortar, and mold stripping means (I) and shelving for stackin~3 the finished panels.

Detailed Description of the Invention Figure 1 shows a building panel 1 having, according to the invention, a structure constituted by a patterned layer 2 which, molded in 25 synthetic resin, forms the patterned surface of the visible face 3 of the panel and constitutes a sort of shell for the panel 1 which comprises the edges 3a.
The said external layer 2 comprises, over the entire inner surtace thereof, an inner layer 4, also of synthetic resin, having l:he entire free 3o surface thereof covered with a solid bulk material 5. The components of this material are firmly embedded in part in said inner layer 4 and provide a substantial free surface area for anchoring the material o~' the resistant body 6 applied thereover, which material fills the entire volume of the said panel shell 1, at the same time as it includes therein reinforcement means 7, in general, which are provided with points directly accessible from the outside of the concealed face 8 of the panel 1, as may be seen in Figures 2,3,5,6and9.
The solid bulk material 5 will preferably be constituted by an aggregate having a large specific area, such as a sand having sharp-edged angular grains, optionally uneroded, without dismissing, notwithstanding, other materials which may be suitable, such as grits, metal reinforcement fibers, metal shavings, etc.
to The points of the reinforcement means 7 accessible from the outside are constituted by parts of said means, or members fixedly attached thereto, projecting out from the resistant body 6 on the concealed face 8 thereof, as may be seen in Figures 5, 6 and 9, forming an external surface to which screws may be applied.
The reinforcement means 7 may be of different shapes, according to the secondary function required of them. Thus, said means may consist of top-hat-shaped metal sections 7A or metal angle sectiors 7B, the latter being those which at the same time constitute the edges 3a of the panel 1, as may be seen in Figures 2 and 5 and in Figures 3, 6, 7, 8 and 9, 2o respectively.
Where the top-hat-shaped metal sections 7A are usE~d, they have a part 9 of the "U" portion projecting out from the surface of the concealed face 8 at the same time as the brim portions 10 thereof arE~ applied to the anchorage surface formed by the solid bulk material 5 and optionally attached thereto, by means of a filler material, such as a resin 11.
Where the metal angle sections 7B are used, the web 12 thereof forms the edge 3a of the panel 1 and is wider than the thickness of the panel 1 and is folded orthogonally over a short distance parallel to the surface of the concealed face 8 of the panel 1 to form an anchoring wing 13 3o for use with screws. The tab 13 may be provided with a stiffening flange 14 directed towards the said concealed face 8. This section also forms a seating wing 10.
In all the cases described, the metal reinforcement sections 7 are provided with apertures 15 in the webs and/or seating wings 10 thereof, which allow for the passage of the mass forming the resistant body 6, so as intimately to embrace part of the body of the metal sections ~'.
The said metal sections 7 will preferably be located longitudinally relative to the panel 1. Nevertheless, some of said metal :>ections 7 may also be located crosswise, in which case a perimetral reinforcement frame will be formed, as may be seen in Figure 7.
Furthermore, the metal sections 7 forming the frame arrangement to shown in Figure 7 may be accompanied by further similar metal sections which may be arranged parallel to one andlor the other of the sides of said frame arrangement.
Furthermore, as shown in Figure 8, the frame and metal section arrangements parallel to one or the other of the sides of the frame comprise corrugated rods 16 which are attached at the ends thereon to said frame arrangements and pass through the intermediate metal reinforcement sections, to which they are attached by welding or other means. These corrugated robs 16 may be accompanied, or replaced, t>y open metal fabrics, lightweight meshes, etc.
2o The resistant body 6 is formed by a material of the group comprising: cement concrete, cement mortar, resin mortar, mixed mortar and synthetic resins, either normal or lightened, alone or in combinations thereof or with other suitable materials, without excluding, therefore, other binding materials, such as lime mortar, plaster, etc.
Said resistant body 6 may be formed by a single layer, or an inner layer 6A of a heavy, air-setting resistant material, for the arn~horage of the patterned layer and of part of the metal reinforcement sections 7, and an outer layer 6B of a lightweight resistant material, completing the thickness of the resistant body 6, conferring a greater thermal ~~nd acoustical 3o insulating power thereon and forming the concealed surface 8 of the panel 1. This outer layer 6B may be preformed as a prefabricated slab of man-made or synthetic lightweight material or by a mixture of both.
The synthetic resin of the patterned layer 3 and of the inner layer 4, forming the shell of the panel 1, consists of a gel-coat of a resin preferably of the group formed by polyesters, polyurethanes, phenolic and epoxy resins, either alone or in combination, incorporating, in all cases, a base coloring agent and, optionally, ornamental and/or distinctive surface coloring arrangements.
Figure 9 illustrates a fragmentary cross section view of one side of an external closure panel 1. It is attached by means of a self-boring self-tapping screw 17 through the anchor wing 13 of the metal angle section 7B
1o to a section 18 of a support structure. The said panel 1 is completed with an inner closure panel 19, of the plasterboard type, with the ensemble forming a wall for a building. Seals 20, which may be made from an elastomer, silicone, etc are provided between the juxtaposed edges of two adjacent panels 1. Raceways, insulation materials, etc., ma~~ conventionally be located between the panel 1 and the panel 19.
The facade panel 21 shown in Figure 10 is constituted by a resistant cement mortar body. Formed as a slab 22, the visible facie 22A and the edges 22B thereof may be formed by another material, such as a synthetic resin, or another quality of the same material, such as a fine cement mortar 2o paste. The visible face 22A may likewise have a smooch texture or a decorated texture with ornamental relief work imitating ;tone masonry, brickwork, wood, marble, etc, with or without color arrangements. The surface of the concealed face 22C will normally be a sirnple smoothed mortar mass.
The facade panel 21 is, furthermore, provided with ~~ reinforcement constituted essentially by top-hat-shaped reinforcement secaions 23 or the like, arranged in such a way that a spine 24, as shown in Figures 10 and 11, or a tab, such as the one as shown in Figures 6, 8 and ~~, each parallel to the concealed face 22C, always projects out from said ~~oncealed face 22C of the slab 22 of the facade panel, and structured in frame-like form with internal stringers 23A and cross members 23B, as shown in Figure 12.
The lattice support structure 25 is constituted by upright sections 26, preferably having a right-angled "C" cross section, of which the longitudinal -1$-half has been illustrated in the majority of the Figures. They are connected together by top-hat-shaped cross member sections 27 having a spine 28 and are attached to the upright sections 26 by screws 29, rivets, welding or other means, forming rigid nodes at the intersections.
According to the invention, it is contemplated that some of the cross members of the reinforcement sections 23B of the facade panels may have the spines 24 confronting and touching the spines 28 of the cross member sections 27 of the lattice structure 25 in the final assembly position thereof, as shown in Figures 11 and 13, thereby allowing them to be attached to together with screws 30, rivets or other mechanical fixation means.
Also, as shown in Figure 10, forming the main feature of the invention, it is contemplated that the spine 24 of the reinforcement sections 23B of the facade panels 21 be extended with an outstanding wing 31 parallel to the concealed face 22C of the slab 22 which, folded over 180°, forms a broad channel 32 which opens downwardly in the final assembly position.
Complementarily to the foregoing, the invention contemplates that the spine 28 of the cross member sections 27 of the lattice structure 25 extend outwardly forming a flange 33 which is directed in the opposite 2o direction to the said broad channel 32 and is housed with a clearance therein in the final assembly position, as shown in Figure 11.
The facade panels 21 may be provided with a safely arrangement against accidental release, consisting of one of the reinforcement sections 23 of the top side of the frame housing longitudinally in the tubular conduit 34 formed by the inner arch of the spine 24 with the concealed face 22C of the slab 22, a loose, resilient, resistant filiform member 35, ;>uch as a steel cable, a chain, etc., of closed contour, which may be firmly anchored to the lattice structure 25. Also, any other arrangement of the filiform member 35, which were not closed, would be adequate.
3o A facade wall made according to the invention is shown in Figure 13. It is to be seen here that the facade panel 21 is provided with two reinforcement sections 23A capable of engaging the corresponding flanges 33 of the cross member sections 27 of the lattice structure 25 by way of the channels 32 thereof. The upright sections 26 of the lattice structure have been drawn completely, with schematic graphic indication of the right-angled C-shaped section thereof.
Figure 13 also shows the arrangement of the internal slabs 36 of compound material, such as plasterboard, fiberboard, etc., which are in any case attached directly by screws 37 to the upright sections ~?6 andlor to the cross member sections 27, forming an insulating air space 38 housing the electricity, gas, water, telephone, etc. lines 39 and comprising a thermally and acoustically insulating fibrous material 40. The internal slabs 36A, as to detailed in Figure 13, constitute the interior surface of the room.
As will be understood, the invention also contemplates the reverse case to the one shown, in which the reinforcement sections 23B are provided with a downwardly directed flange and the cross members 27 are provided with an upwardly open channel 32, in which said flange may is engage.
The clearance 41 provided between the channel 32 and the flange 33 allows the flatness and vertical and horizontal alignment of one facade panel 21 to be adjusted relative to the adjacent facade panels.
The resilient filiform element 35, apart from its mission of assuring 2o the facade panels 1 against accidental falling, may be used as suspension means for the facade panels 21 in the stages of assembly to the lattice structure 25 and handling thereof.
Figure 14 shows the case of a connecting node betv,~een the facade panels 21 and the lattice structure 25. It is to be seen that ;~ reinforcement 2s section 23C of the reinforcement 23 of the facade panel 21 is attached directly to the cross member 27A of the lattice structure 25 by means of the screw 30, which is also self-tapping and self-boring, while the internal slab 36 is mounted directly on the cross member sections 2-~C and upright section 26 of the support structure. In this way, it is possible on the one 3o hand to make independent and assure the direct assembler of the facade panels 21 to said lattice structure 25, which panels are not affected by settling movements of the building, earthquakes, vibrations, etc. which may affect the structure, since they are capable of absorbing the stresses produced by the deformation of the lattice structure 25 c:aused by such movements and, on the other hand, the arrangement of the internal slabs 36 fixed by screws 37 to the wings of the cross members 27A and to the uprights 26 themselves, or to both separately, means that said interior slabs act by compression, in their seat on the cross members 27A and uprights 26 andlor by tension, as struts, whereby the use of said herring-bone struts required in lattice work structures to prevent de1'ormation of the parallelograms forming them, by converting such parallelograms in triangles, is obviated.
io Figure 15 shows two facade panels 21, placed edge-to-edge, forming a conventional wall structure. In this case, the visible faces of the panels imitate brickwork laid in break-joint style, formed by horizontal rectangular relief elements 42, which reproduce the visual effect of a visible longer side of a brick and grooves 43, arranged horizontally relative to the relief elements and vertically, defining the break-joint position and reproducing the conventional mortar joints between them.
Figure 15 also shows the separation joint 44 befiNeen said two panels 21 and two depressed regions 45 which are aligned on both juxtaposed edges, each of which has the shape of half a vi:>ible brick side.
2o These depressed regions 45 have a roughened surface and a shape, when taken together, equivalent to the longer visible face of the trick. A veneer block 46 reproducing the said longer visible side surface of the brick is firmly embedded in said depressed regions with mortar or other material.
Likewise, Figure 16 illustrates two facade panels 21 A in which the visible face imitates natural stone masonry 47 formed by a plurality of relief elements which reproduce the visual effect of stones 47 substantially inlaid and attached by perimetral joints 48.
Also outstanding in Figure 16 is the separation joint 4~E between said panels 21A and two depressed regions 45A which, together, have the 3o shape of a stone. A veneer block 46A reproducing a natural stone 47 is firmly embedded therein with mortar or other material.
It is, therefore, obvious that with the system or arrangement of elements according to the invention, the object of the invention is achieved, assuring the attachment of the facade panels 21 and stabilizing the lattice support structure.
A facade panel 21, appropriate for manufactured in the plant according to the invention, is shown in particular in Figures '15a, 12, and 17 to 19, where it will be seen that it is constituted by a cemeint mortar sheet 22 in which there is embedded a metal reinforcement 23.
The cement mortar slab 22, as shown in Figure 18., may have the visible face 22A and the edges 22B thereof formed by a thin compound layer 49 of a resin (gel coat), or by a simple layer of a fine cement mortar 1o paste, provided in both cases with a pattern constituted by relief elements andlor color associations which configure architectural form:; and/or imitate brickwork, natural stone, masonry, etc. Said layer 49 is firrnly anchored by way of a second layer 50 to the body of the slab made from cement mortar.
Figure 19 shows the case in which the visible face 22A of the facade panel 21 is constituted by the same cement mortar as forms the h~ody of the slab and is provided with normally simple relief elements, such as bush-hammering, graining, etc, to prevent the visible face of 'the panel from appearing to be brightly polished.
Figure 18 shows, further to the construction of the f~yade panel 21, 2o the specific arrangement adopted for the molding thereof, which is formed by a mold carrier device 51, represented by a simple engraved metal sheet, an ornamentally patterned mold 52 of polyurethane, silicone or other materials and side members 53 which act as a frame and lal:erally hold said molds. In this case, the patterned mold 52 reproduces the negative image of the of the ornamentation it is desired to confer on the facade panel 21, such as brickwork, natural stone, masonry, wood, marble, etc.
Likewise, Figure 19 shows the molding arrangement: for the facade panel 21 when the latter is not provided with the thin compound resin or simple cement mortar paste layer 49 and the visible face 22A and the 3o edges 22B are constituted by the cement mortar itself of the body of the slab 22 of the facade panel 21. To this end, the molding arrangement is constituted by the carrier device 51, provided with a simple surface engraving for matting the surface of the visible face 22A of the facade panel and by the side members 53. In this case, the steps obliging the use of the resins, the coarse grains and the polyurethane molds are omitted, whereby the panels are simpler, cheaper and quicker to manufacture. They are of special application in the construction of dignified social dwellings, dispensaries, schools and other constructions in which the external decoration is of secondary importance and only the comfort and security of the building matters.
A plant appropriate for the manufacture of the discl~~sed variations of facade panels 21 is illustrated in Figure 20 and corresponds to an actual 1o premises of about one thousand square meters in area.
The installation of the Figure is provided with a track 54 for the movement of the not shown mold carrier devices, alone or vvith molds. The track, in this case, is constituted by two equal parallel portions 54A and 54B
which are connected at the ends thereof by a transfer table 55 and a work 1 s station h.
The first track portion 54A comprises, successively, the following work stations appropriate for the manufacture of a facade panel 21 having an ornamental visible face, such as the one shown in Figure 20:
(a) means for cleaning the molds, appropriate for removing any 2o mortar and mold stripper remains deposited thereon, (b) means for changing the molds, to be used when the panel to be manufactured has different features from tho:>e of the panel which has been stripped from the mold, which means are complemented by shelving for use as a mold wore, zs (c) means for applying a mold stripping product aver the entire molding surface, (d) means for spraying a thin layer of a first resin (c~el-coat) which waterproofs and enhances the pattern of the visible face of the panel, 30 (e) a tunnel with shelving for storing the molds in the carriers thereof, in stand-by for the curing of the resin sprayed in the molds and/or for the following operation on the mold, (f) means for spraying a thin layer of a second anchor resin on the first resin layer, (g) means for spraying a layer of coarse grained sane, shot, etc. on the second resin layer, so as partly to incrust said coarse grains in the resin and for removing the grains not adhering thereto.
From the first track portion 54A the operation tr,~nsfers to the second track portion 54B by means of the tunnel h with shelving for storage of the carriers bearing the molds charged with both resins ~~nd the coarse to grains incrusted in the second resin, in stand-by for the curing of the second resin and/or the following operation.
The remaining work stations are located on the second track portion 54B:
means for pouring cement mortar, which is prepared from the cement, aggregate, water and additives drawn from silos adjacent the station, (j) means for placing the reinforcement in the cement mortar and, optionally, a suspension cable for the panel anchored in said reinforcement, 2o (k) a tunnel kiln with shelving for the setting of the cement mortar, and mold stripping means and shelving for stacking the finished panels.
On the other hand, for the construction of a facade panel 21 as detailed in Figure 19, the sequence of operative stations would be as follows:
means for cleaning (a) the molding surfaces, appropriate for removing any mortar and mold stripper remains, means for applying (c) a mold stripping product over the entire 3o molding surface, a tunnel (h) with shelving for storing the molds in the carrier devices therefor, in stand-by for the following operation, means for pouring (i) cement mortar, which is preF~ared from the cement, aggregate, water and additives drawn from silos adjacent the station, means for placing (j) the reinforcement in the cement mortar and, optionally, a suspension cable anchored in said reinforcement, a tunnel kiln (k) for the setting of the cement mortar, and mold stripping means (I) and shelving for stackin~~ the finished panels.
Obviously, in the manufacture of the facade panels 21 of the type to shown in Figure 19, specific stations remain inoperative in the: plant and will be operative when manufacturing facade panels 21 like those shown in Figure 18.
When the manufacture of facade panels 21 according to Figure 18 were not contemplated in the plant, this would be reduced to the means and elements listed above and as defined in the second claim.
According to a preferred embodiment of the invention, the track 54 is arranged as a closed circuit on a horizontal plane, specially constituted by two straight, substantially parallel portions 54A and 54B connected together at the ends thereof by a work station h and/or transport means 55.
2o Nevertheless, the two straight portions 54A and 54B could be disposed on parallel superimposed planes.
The track 54 is constituted by a rotating roller path, some of them being motorized.
The plant is completed by shelving 56 for the storage of polyurethane molds, with silos 57 for the cement and aggregate, with tanks 58 for the mortar additives, with a workshop 59 for the reinforcement 23 and with shelving 60 for stacking the finished facade panels ~:1.
The same happens with facade panels imitating natural stone masonry, in which case it is much more difficult to disguise the straight lines of the joints, since the joints between the stones are very irrE~gular and in no case are they straight.
In other cases, which are very frequent in the nevv building trade techniques, it is normal to install internal plasterboard, fiberboard, etc slabs which are used in heterogeneous wall structures to accompany a prefabricated facade panel and form a thermal and acoustical insulation space in cooperation with another similar slab, in this Ease made from plasterboard which, acting as internal closure of the wall, forms the visible face thereof inside the room so formed. Thus, in the building trade, it is a regular practice, particularly in the case of buildings formed by a lattice 2o support structure formed by wooden beams or light metal sections, to attach the facade closure panels to the lattice supponr structure with screws, with the insertion of one of said internal plasterboard, fiberboard panels, etc.
This assembly system has the drawback that the movements due to settling of the structure, to the effects of wind, to snow loads, to seismic movements, structural vibrations, explosions or others cause relative movements between the members of the lattice structure and the facade panels, causing deterioration of said internal slabs by th~~ sawing action caused therein by the ensemble attachment screws, which changes the 3o distance between the lattice structure and the facade panels. As a result, the drawback arises that such panels are placed in a svvaying situation, leading not only to an aesthetic deterioration, but also to the risk of separation and, furthermore, the structure loses the strutting effect offered by said internal slabs.
Lightweight facade panels made substantially by individual molding of a mass of cement mortar with the inclusion of a metallic reinforcement, s such as the embodiments disclosed in Spanish patent 9900369 and utility models 9900014 and 9901847, of the present applicant, arE~ known. These are manufactured in known plants in which to prepare the prefabricated items of mortar or concrete, long heated tracks are used on which the molds are placed. Firstly, the reinforcement members are placed in them 1o and, thereafter, the mortar or concrete is poured and vibrated. After this, the molds are allowed to rest, until a sufficient degree of stating has been attained to be able to strip the molds and stack the pieces obtained until setting is complete.
These plants require large spaces to lay out the tracks, a high 15 energy consumption to heat the tracks, moving means f~~r placing and installing the reinforcement and other, also moving, means ~,~or pouring and vibrating the concrete, all of which means that such plants are extremely burdensome and hardly competitive, to which there should be added the enormous number of molds required for a profitable manufacturing 20 operation.
Summary of the Invention In view of the foregoing, it would be desirable to have a building panel fulfilling the largest number of the following conditions:
25 1. have unbeatable conditions of adhesion of the patterned layer to the material of the resistant body.
2. be provided with reinforcement means whicf i allow it to be attached to a lattice support structure, are easy to produce, may be accurately located and are completely reliable under 30 extreme conditions.
3. coordinate the attachment thereof to the lattice support structure with the attachment of inside wall internal slabs.
, CA 02378769 2002-O1-09 4. comprise a buttstrap arrangement hiding the joints between panels having an architectural pattern.
5. be simple and speedy to manufacture with High quality in a plant which is economical in equipment and labor.
s The building panel of the invention has been developed in accordance with the foregoing solution. Nevertheless, it may have other applications in decoration, industrial and civil protection, etc. In the panel, the molded synthetic resin layer, disposed as a shell ther~:in, is provided over the whole of the inner surface thereof with an internal layer, also of 1o synthetic resin, having the whole of the free surface thereof covered with a solid bulk material, the components of which, having a pact thereof firmly anchored to said internal layer, provide a substantial free surface for the anchorage of the resistant material of the body applied thereover, which material fills the entire volume of said panel shell, at the same time as it 1 s incorporates therein reinforcement means provided with points directly accessible from the outside of the concealed face of the panel.
According to the invention, the solid bulk material is preferably constituted by an aggregate having a large specific surface area and, more precisely, by a sand formed by sharp-edged angular, preferably non-eroded 2o grains. Also comprised within the idea of solid bulk matE:rial are metal shavings, metal fiber reinforcements, grit, etc.
According to the invention, the points of the internal reinforcement means accessible from the outside are located in such a way as to extend clearly from the surface of the concealed face of the panel. In any case, the 2s points of the reinforcement means accessible from the outside are formed by parts of said reinforcement means emerging from the resistant body of the panel on the concealed face thereof. Thus, in a particular case, the reinforcement means comprise flanged top-hat-shaped means having a portion of the U-shaped part thereof projecting from the outside level of the 3o hydraulic material on the concealed face of the panel, and the brim portions thereof are applied against the surface of the solid bulk material.
The invention also contemplates that the reinforcement means comprise metal sections forming the visible portion of the panel edges. One preferred embodiment contemplates that the section constituting the edges of the panel is an angle section and the web thereof is wider than the thickness the edges and is folded orthogonally and in parallel with the surface of the concealed face of the panel to form an anchorage tab which may have a stiffening flange directed towards the surface of said concealed face of the panel.
In all cases, it is deemed desirable that the methyl sections are provided with apertures in the webs andlor seating wings thereof allowing the mass of resistant material of the body to pass therethrough, so as to intimately to embrace a part of the metal section structure.
It is a further feature of the invention that some meval sections are situated lengthwise and others crosswise relative to the panel, forming a frame arrangement. In one case, the metal sections forrning the frame arrangement may be accompanied by other metal sections disposed parallel to one andlor the other of the longer and shorter sides of said frame arrangement and, in all cases, the metal sections comprise corrugated rods transversely crossing said frame and metal section arrangements, said rods being fixedly attached to points thereof, and also optionally accompanied by open mesh wire netting, meshes, etc.
2o According to the invention, the material forming the body resistant to mechanical stresses of the construction is one of the group formed by:
cement concrete, cement mortar, resin mortar, mixed hydraulic and resin mortar, plaster, lime mortar and synthetic resins, either normal or lightened, alone or in combinations thereof.
According to the invention, the resistant body of thE: panel may be formed by an inner layer of a heavy, air-setting resistant material, for the anchorage of the patterned layer and of part of the methyl reinforcement sections, and an outer layer of a lightweight resistant material, completing the body, conferring a greater thermal and acoustical insulating power 3o thereon and forming the concealed surface of the panel. Also according to the invention, the outer layer of the lightweight resistant material may be preformed as a prefabricated slab.
_'j_ According to the invention, the synthetic resin of the layer molded as a shell consists of a gel-coat of a resin of the group formed by polyesters, polyurethanes, phenolic resins and epoxy resins, either alone or in combination, incorporating, in all cases, a base coloring agent and, s optionally, ornamental and/or distinguishing surface coloring arrangements.
One aspect of the invention has a special application, in the building trade, in the above mentioned case of the assembly of the internal plasterboard slabs, fiberboard slabs, etc., where, according to the invention, the internal slab is applied directly, independently of the facade 1o panel, to the support structure, in such a way that it occupies one or more cells thereof and is flanked, in any case, by the corresponding upright and transverse sections, to which it is directly solely attached by screws or other means, at the wings thereof, or to another portion, at end points of the support structure lattice, occupying one or more of the cells thereof, in such 15 a way as to replace the conventional herring-bone strutting.
To avoid the problems appearing in panels having a surface decorated with architectural relief (brickwork, masonry, etc), with a view to disguising the joints between panels, according to the invention the edges of the sides of the panel to be placed juxtaposed to the sides of other 2o panels are provided, at the places on the visible face thereof where the joints cut across the relief of the pattern design, with slightly depressed areas, with those of an adjacent edge of one panel mating with those on the edge of the other panel. Once the panels are installed, these areas define depressed facade areas affecting part or the whole of the joint and in 25 which inserts bearing the design are fitted to form the continuation of the pattern design on the visible faces of the juxtaposed panels.
With a view to manufacturing the panel of the invention under the best conditions, a plant has been devised comprising ~~ track for the movement of carrier devices for the molds forming the facade panel on 3o which there are situated sequentially according to the operative stages required for the manufacture of the facade panel a number of work stations which, defined by the means andlor members pertaining to the work stage proper thereto are listed in order below:
_g_ (a) means for cleaning the molds andlor mold carriers, appropriate for removing any mortar and mold stripper remains deposited thereon, (b) means for changing the molds, to be used only when the s panel to be manufactured has different features from those of the panel which has been stripped from the mold, which means are complemented by shelving for case as a mold store, (c) means for applying a mold stripping product over the entire 1o molding surface, (d) means for spraying over the entire molding surface a thin layer of a first resin (gel-coat) which waterproofs and enhances the pattern of the visible face of the panel, (e) a tunnel with shelving for storing the molds in the carriers ~ 5 thereof, in stand-by for the curing of the resin sprayed in the molds andlor for the following operation on thE; mold, (f) means for spraying a thin layer of a second anchor resin on the first resin layer, (g) means for spraying a layer of coarse grained material (such 2o as sand, shot, etc.) on the second resin layer, so as partly to incrust said coarse grains in the resin and for removing the grains not adhering thereto;
(h) a tunnel with shelving for storage of the carriers bearing the molds charged with both resins and the coarse grains 25 incrusted in the second resin, in stand-by for the curing of the second resin and/or the following operation, (i) means for pouring cement mortar on the second resin and the coarse grains, which is prepared from the cement, aggregate, water and additives drawn from silos adjacent the 30 station, (j) means for placing the reinforcement in the cement mortar and, optionally, a suspension cable for the panel anchored in said reinforcement, (k) a tunnel kiln with shelving for the setting of the cement mortar, and (I) mold stripping means and shelving for stacking the finished panels.
A further feature of the invention resides in the face: that when the architectural features and the resins of the facade panels and, therefore, the polyurethane molds are not used, the molding surface is formed by the bottom wall of the mold carrier devices devoid of said molds, whereby the sequence of operative work stations is reduced to the following:
i0 means for cleaning (a) the mold-free mold carrying devices, appropriate for removing any mortar and mold stripper remains, means for applying (c) a mold stripping product over the entire molding surface, a tunnel with shelving (h) for storing the mold carrier devices, in stand-by for the following operation, means for pouring (i) cement mortar on the molding aurface formed by the mold carrier devices, which is prepared from the cement, aggregate, water and additives drawn from silos adjacent the station, 2o means for placing Q) the reinforcement in the cement mortar and, optionally, a suspension cable for the panel anchored in said reinforcement, a tunnel kiln (k) with shelving for the setting of the cement mortar, and mold stripping means (I) and shelving for stackin~3 the finished panels.

Detailed Description of the Invention Figure 1 shows a building panel 1 having, according to the invention, a structure constituted by a patterned layer 2 which, molded in 25 synthetic resin, forms the patterned surface of the visible face 3 of the panel and constitutes a sort of shell for the panel 1 which comprises the edges 3a.
The said external layer 2 comprises, over the entire inner surtace thereof, an inner layer 4, also of synthetic resin, having l:he entire free 3o surface thereof covered with a solid bulk material 5. The components of this material are firmly embedded in part in said inner layer 4 and provide a substantial free surface area for anchoring the material o~' the resistant body 6 applied thereover, which material fills the entire volume of the said panel shell 1, at the same time as it includes therein reinforcement means 7, in general, which are provided with points directly accessible from the outside of the concealed face 8 of the panel 1, as may be seen in Figures 2,3,5,6and9.
The solid bulk material 5 will preferably be constituted by an aggregate having a large specific area, such as a sand having sharp-edged angular grains, optionally uneroded, without dismissing, notwithstanding, other materials which may be suitable, such as grits, metal reinforcement fibers, metal shavings, etc.
to The points of the reinforcement means 7 accessible from the outside are constituted by parts of said means, or members fixedly attached thereto, projecting out from the resistant body 6 on the concealed face 8 thereof, as may be seen in Figures 5, 6 and 9, forming an external surface to which screws may be applied.
The reinforcement means 7 may be of different shapes, according to the secondary function required of them. Thus, said means may consist of top-hat-shaped metal sections 7A or metal angle sectiors 7B, the latter being those which at the same time constitute the edges 3a of the panel 1, as may be seen in Figures 2 and 5 and in Figures 3, 6, 7, 8 and 9, 2o respectively.
Where the top-hat-shaped metal sections 7A are usE~d, they have a part 9 of the "U" portion projecting out from the surface of the concealed face 8 at the same time as the brim portions 10 thereof arE~ applied to the anchorage surface formed by the solid bulk material 5 and optionally attached thereto, by means of a filler material, such as a resin 11.
Where the metal angle sections 7B are used, the web 12 thereof forms the edge 3a of the panel 1 and is wider than the thickness of the panel 1 and is folded orthogonally over a short distance parallel to the surface of the concealed face 8 of the panel 1 to form an anchoring wing 13 3o for use with screws. The tab 13 may be provided with a stiffening flange 14 directed towards the said concealed face 8. This section also forms a seating wing 10.
In all the cases described, the metal reinforcement sections 7 are provided with apertures 15 in the webs and/or seating wings 10 thereof, which allow for the passage of the mass forming the resistant body 6, so as intimately to embrace part of the body of the metal sections ~'.
The said metal sections 7 will preferably be located longitudinally relative to the panel 1. Nevertheless, some of said metal :>ections 7 may also be located crosswise, in which case a perimetral reinforcement frame will be formed, as may be seen in Figure 7.
Furthermore, the metal sections 7 forming the frame arrangement to shown in Figure 7 may be accompanied by further similar metal sections which may be arranged parallel to one andlor the other of the sides of said frame arrangement.
Furthermore, as shown in Figure 8, the frame and metal section arrangements parallel to one or the other of the sides of the frame comprise corrugated rods 16 which are attached at the ends thereon to said frame arrangements and pass through the intermediate metal reinforcement sections, to which they are attached by welding or other means. These corrugated robs 16 may be accompanied, or replaced, t>y open metal fabrics, lightweight meshes, etc.
2o The resistant body 6 is formed by a material of the group comprising: cement concrete, cement mortar, resin mortar, mixed mortar and synthetic resins, either normal or lightened, alone or in combinations thereof or with other suitable materials, without excluding, therefore, other binding materials, such as lime mortar, plaster, etc.
Said resistant body 6 may be formed by a single layer, or an inner layer 6A of a heavy, air-setting resistant material, for the arn~horage of the patterned layer and of part of the metal reinforcement sections 7, and an outer layer 6B of a lightweight resistant material, completing the thickness of the resistant body 6, conferring a greater thermal ~~nd acoustical 3o insulating power thereon and forming the concealed surface 8 of the panel 1. This outer layer 6B may be preformed as a prefabricated slab of man-made or synthetic lightweight material or by a mixture of both.
The synthetic resin of the patterned layer 3 and of the inner layer 4, forming the shell of the panel 1, consists of a gel-coat of a resin preferably of the group formed by polyesters, polyurethanes, phenolic and epoxy resins, either alone or in combination, incorporating, in all cases, a base coloring agent and, optionally, ornamental and/or distinctive surface coloring arrangements.
Figure 9 illustrates a fragmentary cross section view of one side of an external closure panel 1. It is attached by means of a self-boring self-tapping screw 17 through the anchor wing 13 of the metal angle section 7B
1o to a section 18 of a support structure. The said panel 1 is completed with an inner closure panel 19, of the plasterboard type, with the ensemble forming a wall for a building. Seals 20, which may be made from an elastomer, silicone, etc are provided between the juxtaposed edges of two adjacent panels 1. Raceways, insulation materials, etc., ma~~ conventionally be located between the panel 1 and the panel 19.
The facade panel 21 shown in Figure 10 is constituted by a resistant cement mortar body. Formed as a slab 22, the visible facie 22A and the edges 22B thereof may be formed by another material, such as a synthetic resin, or another quality of the same material, such as a fine cement mortar 2o paste. The visible face 22A may likewise have a smooch texture or a decorated texture with ornamental relief work imitating ;tone masonry, brickwork, wood, marble, etc, with or without color arrangements. The surface of the concealed face 22C will normally be a sirnple smoothed mortar mass.
The facade panel 21 is, furthermore, provided with ~~ reinforcement constituted essentially by top-hat-shaped reinforcement secaions 23 or the like, arranged in such a way that a spine 24, as shown in Figures 10 and 11, or a tab, such as the one as shown in Figures 6, 8 and ~~, each parallel to the concealed face 22C, always projects out from said ~~oncealed face 22C of the slab 22 of the facade panel, and structured in frame-like form with internal stringers 23A and cross members 23B, as shown in Figure 12.
The lattice support structure 25 is constituted by upright sections 26, preferably having a right-angled "C" cross section, of which the longitudinal -1$-half has been illustrated in the majority of the Figures. They are connected together by top-hat-shaped cross member sections 27 having a spine 28 and are attached to the upright sections 26 by screws 29, rivets, welding or other means, forming rigid nodes at the intersections.
According to the invention, it is contemplated that some of the cross members of the reinforcement sections 23B of the facade panels may have the spines 24 confronting and touching the spines 28 of the cross member sections 27 of the lattice structure 25 in the final assembly position thereof, as shown in Figures 11 and 13, thereby allowing them to be attached to together with screws 30, rivets or other mechanical fixation means.
Also, as shown in Figure 10, forming the main feature of the invention, it is contemplated that the spine 24 of the reinforcement sections 23B of the facade panels 21 be extended with an outstanding wing 31 parallel to the concealed face 22C of the slab 22 which, folded over 180°, forms a broad channel 32 which opens downwardly in the final assembly position.
Complementarily to the foregoing, the invention contemplates that the spine 28 of the cross member sections 27 of the lattice structure 25 extend outwardly forming a flange 33 which is directed in the opposite 2o direction to the said broad channel 32 and is housed with a clearance therein in the final assembly position, as shown in Figure 11.
The facade panels 21 may be provided with a safely arrangement against accidental release, consisting of one of the reinforcement sections 23 of the top side of the frame housing longitudinally in the tubular conduit 34 formed by the inner arch of the spine 24 with the concealed face 22C of the slab 22, a loose, resilient, resistant filiform member 35, ;>uch as a steel cable, a chain, etc., of closed contour, which may be firmly anchored to the lattice structure 25. Also, any other arrangement of the filiform member 35, which were not closed, would be adequate.
3o A facade wall made according to the invention is shown in Figure 13. It is to be seen here that the facade panel 21 is provided with two reinforcement sections 23A capable of engaging the corresponding flanges 33 of the cross member sections 27 of the lattice structure 25 by way of the channels 32 thereof. The upright sections 26 of the lattice structure have been drawn completely, with schematic graphic indication of the right-angled C-shaped section thereof.
Figure 13 also shows the arrangement of the internal slabs 36 of compound material, such as plasterboard, fiberboard, etc., which are in any case attached directly by screws 37 to the upright sections ~?6 andlor to the cross member sections 27, forming an insulating air space 38 housing the electricity, gas, water, telephone, etc. lines 39 and comprising a thermally and acoustically insulating fibrous material 40. The internal slabs 36A, as to detailed in Figure 13, constitute the interior surface of the room.
As will be understood, the invention also contemplates the reverse case to the one shown, in which the reinforcement sections 23B are provided with a downwardly directed flange and the cross members 27 are provided with an upwardly open channel 32, in which said flange may is engage.
The clearance 41 provided between the channel 32 and the flange 33 allows the flatness and vertical and horizontal alignment of one facade panel 21 to be adjusted relative to the adjacent facade panels.
The resilient filiform element 35, apart from its mission of assuring 2o the facade panels 1 against accidental falling, may be used as suspension means for the facade panels 21 in the stages of assembly to the lattice structure 25 and handling thereof.
Figure 14 shows the case of a connecting node betv,~een the facade panels 21 and the lattice structure 25. It is to be seen that ;~ reinforcement 2s section 23C of the reinforcement 23 of the facade panel 21 is attached directly to the cross member 27A of the lattice structure 25 by means of the screw 30, which is also self-tapping and self-boring, while the internal slab 36 is mounted directly on the cross member sections 2-~C and upright section 26 of the support structure. In this way, it is possible on the one 3o hand to make independent and assure the direct assembler of the facade panels 21 to said lattice structure 25, which panels are not affected by settling movements of the building, earthquakes, vibrations, etc. which may affect the structure, since they are capable of absorbing the stresses produced by the deformation of the lattice structure 25 c:aused by such movements and, on the other hand, the arrangement of the internal slabs 36 fixed by screws 37 to the wings of the cross members 27A and to the uprights 26 themselves, or to both separately, means that said interior slabs act by compression, in their seat on the cross members 27A and uprights 26 andlor by tension, as struts, whereby the use of said herring-bone struts required in lattice work structures to prevent de1'ormation of the parallelograms forming them, by converting such parallelograms in triangles, is obviated.
io Figure 15 shows two facade panels 21, placed edge-to-edge, forming a conventional wall structure. In this case, the visible faces of the panels imitate brickwork laid in break-joint style, formed by horizontal rectangular relief elements 42, which reproduce the visual effect of a visible longer side of a brick and grooves 43, arranged horizontally relative to the relief elements and vertically, defining the break-joint position and reproducing the conventional mortar joints between them.
Figure 15 also shows the separation joint 44 befiNeen said two panels 21 and two depressed regions 45 which are aligned on both juxtaposed edges, each of which has the shape of half a vi:>ible brick side.
2o These depressed regions 45 have a roughened surface and a shape, when taken together, equivalent to the longer visible face of the trick. A veneer block 46 reproducing the said longer visible side surface of the brick is firmly embedded in said depressed regions with mortar or other material.
Likewise, Figure 16 illustrates two facade panels 21 A in which the visible face imitates natural stone masonry 47 formed by a plurality of relief elements which reproduce the visual effect of stones 47 substantially inlaid and attached by perimetral joints 48.
Also outstanding in Figure 16 is the separation joint 4~E between said panels 21A and two depressed regions 45A which, together, have the 3o shape of a stone. A veneer block 46A reproducing a natural stone 47 is firmly embedded therein with mortar or other material.
It is, therefore, obvious that with the system or arrangement of elements according to the invention, the object of the invention is achieved, assuring the attachment of the facade panels 21 and stabilizing the lattice support structure.
A facade panel 21, appropriate for manufactured in the plant according to the invention, is shown in particular in Figures '15a, 12, and 17 to 19, where it will be seen that it is constituted by a cemeint mortar sheet 22 in which there is embedded a metal reinforcement 23.
The cement mortar slab 22, as shown in Figure 18., may have the visible face 22A and the edges 22B thereof formed by a thin compound layer 49 of a resin (gel coat), or by a simple layer of a fine cement mortar 1o paste, provided in both cases with a pattern constituted by relief elements andlor color associations which configure architectural form:; and/or imitate brickwork, natural stone, masonry, etc. Said layer 49 is firrnly anchored by way of a second layer 50 to the body of the slab made from cement mortar.
Figure 19 shows the case in which the visible face 22A of the facade panel 21 is constituted by the same cement mortar as forms the h~ody of the slab and is provided with normally simple relief elements, such as bush-hammering, graining, etc, to prevent the visible face of 'the panel from appearing to be brightly polished.
Figure 18 shows, further to the construction of the f~yade panel 21, 2o the specific arrangement adopted for the molding thereof, which is formed by a mold carrier device 51, represented by a simple engraved metal sheet, an ornamentally patterned mold 52 of polyurethane, silicone or other materials and side members 53 which act as a frame and lal:erally hold said molds. In this case, the patterned mold 52 reproduces the negative image of the of the ornamentation it is desired to confer on the facade panel 21, such as brickwork, natural stone, masonry, wood, marble, etc.
Likewise, Figure 19 shows the molding arrangement: for the facade panel 21 when the latter is not provided with the thin compound resin or simple cement mortar paste layer 49 and the visible face 22A and the 3o edges 22B are constituted by the cement mortar itself of the body of the slab 22 of the facade panel 21. To this end, the molding arrangement is constituted by the carrier device 51, provided with a simple surface engraving for matting the surface of the visible face 22A of the facade panel and by the side members 53. In this case, the steps obliging the use of the resins, the coarse grains and the polyurethane molds are omitted, whereby the panels are simpler, cheaper and quicker to manufacture. They are of special application in the construction of dignified social dwellings, dispensaries, schools and other constructions in which the external decoration is of secondary importance and only the comfort and security of the building matters.
A plant appropriate for the manufacture of the discl~~sed variations of facade panels 21 is illustrated in Figure 20 and corresponds to an actual 1o premises of about one thousand square meters in area.
The installation of the Figure is provided with a track 54 for the movement of the not shown mold carrier devices, alone or vvith molds. The track, in this case, is constituted by two equal parallel portions 54A and 54B
which are connected at the ends thereof by a transfer table 55 and a work 1 s station h.
The first track portion 54A comprises, successively, the following work stations appropriate for the manufacture of a facade panel 21 having an ornamental visible face, such as the one shown in Figure 20:
(a) means for cleaning the molds, appropriate for removing any 2o mortar and mold stripper remains deposited thereon, (b) means for changing the molds, to be used when the panel to be manufactured has different features from tho:>e of the panel which has been stripped from the mold, which means are complemented by shelving for use as a mold wore, zs (c) means for applying a mold stripping product aver the entire molding surface, (d) means for spraying a thin layer of a first resin (c~el-coat) which waterproofs and enhances the pattern of the visible face of the panel, 30 (e) a tunnel with shelving for storing the molds in the carriers thereof, in stand-by for the curing of the resin sprayed in the molds and/or for the following operation on the mold, (f) means for spraying a thin layer of a second anchor resin on the first resin layer, (g) means for spraying a layer of coarse grained sane, shot, etc. on the second resin layer, so as partly to incrust said coarse grains in the resin and for removing the grains not adhering thereto.
From the first track portion 54A the operation tr,~nsfers to the second track portion 54B by means of the tunnel h with shelving for storage of the carriers bearing the molds charged with both resins ~~nd the coarse to grains incrusted in the second resin, in stand-by for the curing of the second resin and/or the following operation.
The remaining work stations are located on the second track portion 54B:
means for pouring cement mortar, which is prepared from the cement, aggregate, water and additives drawn from silos adjacent the station, (j) means for placing the reinforcement in the cement mortar and, optionally, a suspension cable for the panel anchored in said reinforcement, 2o (k) a tunnel kiln with shelving for the setting of the cement mortar, and mold stripping means and shelving for stacking the finished panels.
On the other hand, for the construction of a facade panel 21 as detailed in Figure 19, the sequence of operative stations would be as follows:
means for cleaning (a) the molding surfaces, appropriate for removing any mortar and mold stripper remains, means for applying (c) a mold stripping product over the entire 3o molding surface, a tunnel (h) with shelving for storing the molds in the carrier devices therefor, in stand-by for the following operation, means for pouring (i) cement mortar, which is preF~ared from the cement, aggregate, water and additives drawn from silos adjacent the station, means for placing (j) the reinforcement in the cement mortar and, optionally, a suspension cable anchored in said reinforcement, a tunnel kiln (k) for the setting of the cement mortar, and mold stripping means (I) and shelving for stackin~~ the finished panels.
Obviously, in the manufacture of the facade panels 21 of the type to shown in Figure 19, specific stations remain inoperative in the: plant and will be operative when manufacturing facade panels 21 like those shown in Figure 18.
When the manufacture of facade panels 21 according to Figure 18 were not contemplated in the plant, this would be reduced to the means and elements listed above and as defined in the second claim.
According to a preferred embodiment of the invention, the track 54 is arranged as a closed circuit on a horizontal plane, specially constituted by two straight, substantially parallel portions 54A and 54B connected together at the ends thereof by a work station h and/or transport means 55.
2o Nevertheless, the two straight portions 54A and 54B could be disposed on parallel superimposed planes.
The track 54 is constituted by a rotating roller path, some of them being motorized.
The plant is completed by shelving 56 for the storage of polyurethane molds, with silos 57 for the cement and aggregate, with tanks 58 for the mortar additives, with a workshop 59 for the reinforcement 23 and with shelving 60 for stacking the finished facade panels ~:1.
